This is a GLOCK OEM frame complete with all stock parts necessary for function. This lower assembly is configured for use with full size .40 S&W and .357 SIG upper assemblies. GLOCK factory slides and receivers are items we receive on an infrequent basis. As they are high demand items, frequent back-orders and significant wait times may occur. Upon arrival we dedicate these slides and receivers starting with the oldest order, working our way to the newest order placed. Wait times vary by demand and by the number of the items received.
